Description
Technical Field
The utility model relates to a mariculture wastewater treatment device, and belongs to the technical field of sewage treatment.
Background
With the rapid development of the mariculture industry, the discharge amount of the mariculture wastewater is remarkably increased, and the problems therewith are increasingly obvious. The direct discharge of pollutants in mariculture wastewater without effective treatment can seriously pollute the water body and even destroy the ecological balance of the ocean. Because the quality of the mariculture wastewater is complex, how to effectively treat nitrogen, phosphorus and COD in the mariculture wastewater is a hotspot and a difficulty of current research. In order to realize the continuous and healthy development of the mariculture industry, a cheap, efficient and safe mariculture wastewater treatment method is urgently needed, and the mariculture wastewater is purified and then discharged up to the standard, so that the coordinated development of mariculture and marine environment protection is realized.
At present, the conventional physicochemical combined technology is researched more, but the structure mainly based on the conventional treatment method has certain defects. For example, application No. 201920621345.7 discloses a mariculture wastewater treatment device, which utilizes microwave to promote the culture wastewater and medicament to generate flocculation and precipitation, thereby purifying the mariculture wastewater. Although the patent has good flocculation effect, the treatment method mainly relying on adding medicaments has limited effect, the effluent quality cannot be ensured, and the addition of the flocculating agent is easy to cause secondary pollution. Application patent No. 201720793806.X discloses an electrolytic nitrogen and phosphorus removal device, which has the effect of removing nitrogen, phosphorus and COD, but consumes a large amount of electric energy, and the water inlet mode is not favorable for sufficient contact of pollutants and the electrolytic device. In contrast, biological treatment is considered to be a preferred method, and although structures based on biological treatment are effective in wastewater treatment, such devices are generally complicated in structure and occupy a large area. For example, in the chinese utility model with application No. 201920172501.6, a mariculture wastewater treatment device is disclosed, which comprises a biological aerated filter, a membrane bioreactor, a first aeration component and a second aeration component, and the device has poor environmental impact resistance and membrane pollution. In the chinese utility model patent of application patent No. 201420655436.X, an artificial wetland system for mariculture waste water treatment is disclosed, it mainly includes equalizing basin, acidizing hydrolysis tank, wetland region and play pond. Although the system can effectively treat pollutants, the system has long running period and slow effect and cannot effectively treat the wastewater in a short time.
